This invention has forits obiecta frame unit by means of which 'scafiolding, shoring supports, forms for concrete work and the; like can be readily constructed and knocked down and the units re-usecl, "which unit'consists of a main member which may be used as a strut or a cross beam and end members or coupling pieces, one of which is interchangeably mountable either on the end of the main member or on the side thereof at various heights, so that a frame work forscafiolding shorings, towers, etc., of almostany form can be made from the units. a

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and; claimed.

In describing this invention reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

This unit comprises generally a. main member formed with a lengthwise slot and having a lengthwisetongue at one end in line with the slotand a socket at its other end for receiving a coupling piecein the form of a tongue and a coupling piece interchangea lengthwise slot 2, these strips being usually 1:333. Serial No. 550,727.

ably mountable on the tongue and on the side i I faces of the body, this coupling piece having a stem which is bifurcated-for receiving the tongues and a head for'engaging a side face of the main body with the bifurcated an, stem extending laterally'from the main body to receive a tongue of another unit. ii

1 designates the main body which is. formed up of opposing strips spaced apart toform some form .of angle iron, they being prefer: ably channel irons arranged with their backs opposed to each other to 'form the side walls of theslot 2. The strips are held spacedapart to provide the slot 2 in anysuitable manner as by spacers' 4 designates a tongue at one end of th body, thetongue being provided with a bifurcated base 5; the branches of which lie in the end portions of the channels of the strips and ,9;

which are secured to theb'ottom of thech'an-c nel in any suitable manner as by rivets The tongue at is in line with the'slot 2. i I i 7 is the socket member arranged at theopr the tongue 4 is located, this being arranged to receive thetongue 4 of another main body or a demountable tongue or coupling pieced in order to adapt this end of tlie'body to receive a "i shaped coupling piece to be presently described. The socket member 7 isin the form of a head or box formed with a socket positeend of the main body 1 tothat on which lg;

. in line with the slot 2 and having legs or plates 9 arranged to lap the bottom flanges of the channel iron 1 and secured thereto n it? any suitable manner as by rivets 10.

11 is'a coupling piece having a-bifurcated stem or leg 12 and 'a head 13, the bifurcated leg' being for/the purpose of receiving the tongue 4 and to be detachably secured there- 99 to in any suitable manner as by'bolt-s 14. This coupling piece 11 isusually shaped and is interchangeably mountable on theend of the body 1 with its bifurcatedleg rec'eiving the tongue 4 or with its head abutting against a side face of the body 1, so that its leg projects at a right angle to the body 1 for receiving thetong-ue 4 ofanother unit arranged in horizontal position." The head is preferably formed with corrugationsasshown at 15 for ago coacting with teeth 16 extending lengthwise of the body 1 on opposite sides of the slot, the

p are engaged.

the coupling piece 11 is held on by one bolt,-

the interlocking corrugations 15 and teeth 16 The socket piece 7 is also formed with teeth 16 forming continuations of the teeth 16 of the main member 1. 7

In Figures'l and 2, the unit is shown as in upright position or as a pillar with the socket member 7 serving asa foot piece and the T shaped coupling member llfas coupled to a member 1 arranged in horizontal position by the bolt 21 extending through the slot 2 of the body of the main member arranged in horizontal position. The construction shown in Figures 1 and 2. is adapted to support shorings for floors.

' In'Figure 3, two main members arev shown as arranged end to end and coupled together by the socket or foot piece 7 at the end'oi onemain member and the tongue 4 at the end I of the other main'member.

In Figure 4, two mam members are shown as lapping each other or spliced-together by having the teeth 16 engaged and the two members clamped together through the slots 2by means of bolts :22.

In Figure 5, an arrangement is shown of.

the horizontal members when the units are used to form shorings or a mould for. a-square pillar. The T shaped pieces 11 at the ends f of each member are coupled or secured to a side face of the adjacent members in the man- ,ner shown in the upper end of Figure 2.

WVhen a T shaped piece is to be provided at each end of a main membeiya tongue or coupling piece 8 is inserted in the foot piece or socket member 7 ,as shown in the lower end of Figure 7 so that a T shaped coupling-piece can be mounted on the projecting end of the coupling piece or tongue 8 and bolted thereto.

In Figures 6, the form is shown for supporting the shorings of a concretewall and the horizontal members are secured to the .vertical members as shown at 25, also spreaders 26 are shownas connected to the ends of the bolts which secure thehorizontal members 1 to the upright members 1.

- It is obvious that by reason of this unit consisting of a main body 1 of channel iron having the tongues 4 and socket piece 7 and the T shaped coupling piece 11 and tonguesS, an indefinite number of arrangements is p0ssible for forming walls, columns, floor forms, wall forms, scaffolding, towers, etc.
